We began class by using the Quadratic Formula to find the number of x-intercepts of the graphs of three quadratic equations. This led us to consider the discriminant of a quadratic. We then corrected homework questions and finished by fixing up the MELMAC sheets (this is the list of occupations- it works well to use your browser's search function).
Organize the homework for Unit 10 and revise for Tuesday's test
Wednesday, May 27, 2009
We began class with a warm up of finding the x-intercepts of y = x² – 8x + 6 by completing the square. We checked the answer on the calculator.

Look at your Quarter 2, Midterm Exam, and Semester grades in Powerschool- are there any mistakes in my calculations? Keep in mind that this is not necessarily your final grade, but if reflects my raw calculations up to this point.
After discussing the previous semester and advice for the coming semester, we paused for a moment to appreciate the chance to begin again, to have a fresh start. We then began Unit 7 with a look at the exam scaling and how this is an example of a system of equations. We ended with a couple of examples of solving systems of equations by graphing.
HW:
Take a look back over your Course Outline (course_methodology.pdf) in preparation for your fresh start to the semester.
Skim over the Key Skills for Unit 6 on p. 310-312 (except for Lesson 6.4- the key skill here is graphing, not domain and range). Come prepared on Wednesday with questions on anything you don't feel 100% comfortable with.
Because of the snow days, you will only need to have the first two assignments from Unit 6 ready to be handed in with your midterm: p. 280/15-35 odd; 36-40, 43-46 & p. 286/31-65 odd; 67, 69, 71. Please finish up the remainder for after midterms- they will be due at the end of the first week back.
